NOTE!
Under-voltage protection creates an open circuit, removing voltage from the termi-
nals� With a lead-acid battery, finding no voltage at the terminals often indicates the
battery has reached the end of its life� With the LifePo4 module, low voltage at the
terminals typically means the cell protection circuitry has interrupted current to pro-
tect the battery module� Simply connect the module to a charger to restore voltage
to the terminals�
OVER TEMPERATURE
A battery module has one temperature sensor to measure every cell bank's tempe-
rature and one PCBA to measure MOSFET temperature�
• The ideal hardware over temperature protection threshold of cell is around +65°C
• The ideal hardware over temperature protection threshold of MOSFET is around
+85°C
During charging and discharging, when any cell banks temperature >60°C, software
over temperature protection appears, charge and discharges MOSFETS turn OFF�
When any cell banks temperature < 55°C, over temperature protection disappear,
charge and discharges MOSFETS turn ON again�
When any cell banks temperature > 65°C, hardware over temperature protection
appear, charge and discharge MOSFETS turn OFF� When the temperature decreases
to 55°C, the charge and discharge MOSFETS turn ON again�
BALANCING
Over time, the cells inside a battery pack diverge in both capacity and SOC� An
advantage of the module is the circuitry continuously monitors the capacity and
SOC of each individual cell and balances the battery module to ensure maximum
capacity�
